predator shift points

I was wondering after reading that the power band of the predator is in the lower rpm range, that the shift points are set so that it shifts before the power curve flattens out. Stock seems to be at 3500 and 3250.
I ask because I cant see stretching the rpms out in a diesel,JUSTmy opinion.
thanks.

Same thing here

I used to be able to precisely predict each shift point on my old 5.4...I knew exactly where each one was at full throttle with my SCMT (46, 72, 102)

Anticipating the shifts on a chipped 6.0 is like trying to predict the impact of a hammer drill

I can't even tell at what speed it will downshift and when it wont.

so what you guys are saying is that it never seems to pull too long in any gear (this might seem dumb to ask but I mostly drive a stick

Not so much that it won't pull too long in any gear, but that it goes through them so quick!

You guys need to hook on a trailer big enough to slow down the truck enough so that you can check the revs at the shift point.

Unloaded with my pokey old SCMT I still have enough time to catch where the shift points are. Though that's probably from years worth of motorcycle racing experience. Spend a lot of time watching the tach out of the corner of your eye. If you think the shifts fly by quickly on a 6.0 . . .

At part throttle (up to about half throttle where things happen a bit faster) I feel it is just like the stock shifting...

again - if I do something hokey like throttle up just before a shift point (or throttle down quickly) the tranny tries to guess at what the heck I'm wanting to do... but with regular and smotth application - works fine...

Thanks !
but I think I'm done after the turbo back and the predator...
it runs as fast as I want an 8k lb tank to go

any more power and I wonder about overpowering the tranny -
and it's just to make my daily driver a wee bit more fun

course that water injection thread has me thinking....
and motorhaven has comes out with some new toys....

so....... ?

I know what you mean, now the brakes don't work because we are going so much faster. I kid you not, I pulled a car length on my buddy in his Lexus GS400 (300hp sedan) when I ran my Quadzilla in 160. We ran to 90 mph. It is crazy having a truck so fast.
